chore: merge upstream with local feature additions

- Merged dexscreener connector, composio connectors, crypto realtime tools from upstream
- Kept local additions: dropbox/onedrive connectors, memory routes, model_list routes, RefreshToken model
- Resolved frontend conflicts: kept tool UIs from both sides
- Accepted upstream lock files (uv.lock, pnpm-lock.yaml)
